No links to Corvette forums as far as I know. The only danger of posting a link to used parts is if it interferes with what one of our supporting vendors sells. As no one sells used parts as a business, it should be good. However, we would appreciate people trying to locate parts with Corvette Central, Manny, or Addison Chevrolet first...but if they don't have used parts for you, what can I say, give car-parts a shot.
There is also a difference between someone posting a link to a site they find very beneficial and someone who owns a business posting a link to their own site in pursuit of advertising their business. If you think people should know about car-parts and you don't have any vested interest in the company, post away! Just make sure it doesn't step on the toes of any supporting vendors.
